通常当我运行flutter build apk --split-per-abi时。它为不同的架构输出三个apk版本。
但这次我运行相同的命令，它只输出一个apk，即armeabi-v7a
控制台输出：
PS C:UsersmapleDocumentsAndroid Stuffbmi_calculator> flutter build apk --split-per-abi
Running Gradle task 'assembleRelease'...

编辑；现在可以了，没什么大不了的，只是输出生成文件的工具有问题。
你可以试试这个
flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi
